Blade Division FAQ

Remove all burrs from edges and from around holes. No sharp edges for safety reasons; please plan to finish grind after the heat treating process. Sharp spines are acceptable.

A hole in the tang is helpful during processing, allowing us to hang the blades vertically. The hole should be at least 1/8” in diameter.

Cutting edge thickness is important in order to help prevent the edge from warping in a wave pattern. This warpage cannot be corrected after it occurs. Non-aggressive and symmetrical grinding will help to reduce stress and warpage. The grit size does not matter, whatever the maker is comfortable with.

The following grind stock should be left on the edge of the blades:

  • Air hard edge thickness: 0.015” minimum
  • Oil hard edge thickness: 0.030” minimum

Be sure to include a Customer Sheet in the package with your blades. The information on this form tells us whose account the job is for and gives us processing instructions. Excluding this information will add time to the turnaround of your order.

Package your knives securely in the box so that they cannot move. They will cut themselves out of the box if they can slide or shift. Wrapping in newspaper or similar material works well. Putting a protective covering (such as cardboard) over the blade tip & edge will help to prevent damage during shipping.

Include instructions along with your blades regarding steel type, hardness requirements and any other special needs using the Customer Sheet.

We will return ship using the same method in which we received the blades unless otherwise instructed. We can ship USPS or UPS. Please advise on the Customer Sheet if express shipping or insurance is needed for the return trip. Insurance will not be included on return shipping unless it is requested on this sheet. Customer bears risk of loss during transportation and shall maintain appropriate insurance to cover such risk of loss.

Due to our premium service approach, return delivery is typically 4 weeks. However, lead time can increase during holiday seasons and due to team vacations. Please check back on the website as we do our best to post all delays.

Custom blade order payment is due upon completion of the work so an up-to-date credit card must be on file. You must have credit card information on file. The return shipping will be added to your processing total and charged to your card prior to return shipment of your order. Please include your credit card information on page 2 of the Customer Sheet. You can also call 814-333-1782 to update the card information on file.

• Oil hard maximum capacity is 24” in length.
• All other steels maximum capacity is 50” in length.

We will harden to the customer’s requested hardness unless we feel that the request is unrealistic, in which case the customer will be contacted to discuss options.

If you are unsure what hardness is best for your material please note that you would like a recommendation on your Customer Sheet and we will heat treat to the appropriate hardness based on your material type.

We aim to hardness test where we feel from experience is least likely to show. If you would like the testing to happen in a particular place, please let us know on your Customer Sheet when you send your order. If you would like us not to test your blades please send an extra piece of the same material with your order that we can use as a test piece (and note the request on your Customer Sheet).

We are not comfortable returning your work without hardness testing as it is our job to supply quality material heat treated to the proper hardness.

Almost all blades warp a little during the hardening cycle. We will do all that we can during processing to reduce or eliminate warpage.

The customer will be informed of any blades that we feel are warped beyond our expectation prior to return shipping.

Our straightening methods employ low heat and pressure and this may leave heat marks on your blades. We try to reduce the impact on the surface, but we cannot eliminate it completely.  Peters’ Heat Treating Blade Division is not responsible for surface finish blemishes on knives with less than 0.010″ grind stock. Straightening methods vary based on blade alloy/geometry/other factors and this may present during secondary finishing operations if not reviewed. Please note on your Customer Form sent with your job if straightening should be omitted to minimize any issues with surface blemishes.

Each steel grade is a separate order.  Same steel grade but different hardness is also a separate order.
